TPS25200DRVT

The TPS25200DRVT is a 6.5V eFuse with precision current limit and overvoltage clamp. The device provides robust protection for load and source during overvoltage and over-current events. The TPS25200 is an intelligent protected load switch with VIN tolerant to 20V. In the event that an incorrect voltage is applied at IN, the output will clamp to 5.4V to protect the load. If the voltage at IN exceeds 7.6V, the device disconnects the load to prevent damage to the device and/or load. The TPS25200 has an internal 60mΩ power switch and is intended for protecting source, device and load under a variety of abnormal conditions. The device provides up to 2.5A of continuous load current. Current limit is programmable from 85mA to 2.9A with a single resistor to ground. During overload events output current is limited to the level set by RILIM. If a persistent overload occurs the device will eventually go into thermal shutoff to prevent damage to the TPS25200.
